Well said, the point of doubly linked lists is not that it is the be all and end all of all data structures. You can possibly workaround that. The real issue is a real program has much more complex data structures, how can you possibly make it work or refactor easily when a simple thing like DLL's are causing so much grief. So, yeah Rust really is unproductive in a massive way. Just useful in small parts where you might really need memory safety (that too, not sure why you wouldn't chose another language).
